Abstract
This invention relates to a keyboard switch assembly having a minimal number of components. A flexible printed circuit cable is configured in such a manner so that the flexible printed circuit cable contains complementary overlapping contact points interconnected by printed circuit electrical lines. A spacer plate with apertures corresponding to sets of complementary contact points is interposed between segments of the folded flexible printed circuit cable. A method for making a keyboard switch assembly with a flexible printed circuit multiple switch assembly is disclosed.
